把代码贴上来看下。

#include <opencv2/opencv.hpp>

#include <opencv2/xfeatures2d.hpp>

#include <iostream>



using namespace cv;

using namespace std;

using namespace cv::xfeatures2d;



int main()

{

	system("color 5F");



	Mat trainImage = imread("D:\\O\\cst\\07.jpg");

	imshow("原始图", trainImage);



	Mat trainImage_gray;

	cvtColor(trainImage, trainImage_gray, CV_BGR2GRAY);



	vector<KeyPoint> train_keyPoint;

	Mat trainDescription;

	SiftFeatureDetector featureDetetor;

	featureDetetor.detect(trainImage_gray, train_keyPoint);

	SiftDescriptorExtractor featureExtractor;

	featureDetetor.compute(trainImage_gray, train_keyPoint, trainDescription);



	BFMatcher matcher;

	vector<Mat> train_desc_collectin(1, trainDescription);

	matcher.add(train_desc_collectin);

	matcher.train();



	VideoCapture cap(0);

	unsigned int frameCount = 0;



	while (char(waitKey(1)) != 'q')

	{

		double time0 = getTickCount();

		Mat captureImage, captureImage_gray;

		cap >> captureImage;

		if (captureImage.empty())

			continue;



		cvtColor(captureImage, captureImage_gray, CV_BGR2GRAY);

		

		vector<KeyPoint> test_keyPoint;

		Mat testDescriptor;

		featureDetetor.detect(captureImage_gray, test_keyPoint);

		featureExtractor.compute(captureImage_gray, test_keyPoint, testDescriptor);



		vector<vector<DMatch>> matches;

		matcher.knnMatch(testDescriptor, matches, 2);



		vector<DMatch> goodMatches;

		for (double k = 0; k < matches.size(); k++)

		{

			if (matches[k][0].distance < 0.6 * matches[k][1].distance)

				goodMatches.push_back(matches[k][0]);

		}



		Mat dstImage;

		drawMatches(captureImage, test_keyPoint, trainImage, train_keyPoint, goodMatches, dstImage);

		imshow("匹配窗口", dstImage);



		cout << "当前帧率为：" << getTickFrequency() / (getTickCount() - time0) << endl;

	}



	return 0;
